Magnetic Resonance Imaging (MRI)

• Sometimes your MRI test results may be different from the results of CT, ultrasound, or X-ray tests, because the MRI scan shows tissue differently.
• MRI is a safe test for looking at structures and organs inside the body. It costs more than other methods and may not be available in your area.
• Open MRI machines are now made so that the magnet does not completely surround you. But these machines may not be available in all medical centers. Open MRI is useful for people who are claustrophobic or obese.
• MRI can be used to check different parts of the body, such as the head, belly, breast, spine, shoulder, and knee. For more information, see the topics Reference MRI of the Head, Reference MRI of the Abdomen, Reference MRI of the Breast, Reference MRI of the Spine, Reference MRI of the Shoulder, and Reference MRI of the Knee.
• Magnetic resonance angiogram (MRA) is a special MRI method that studies blood vessels and blood flow. For more information, see the topic Reference Magnetic Resonance Angiogram (MRA).
• MRI spectroscopy is a special MRI method that identifies certain medical problems by looking for specific chemicals in body tissues.
• Reference Contrast material Opens New Window that contains gadolinium may cause a serious skin problem (called nephrogenic fibrosing dermopathy) in people with Reference kidney failure Opens New Window. Before having an MRI scan, tell your doctor if you have serious kidney disease or if you have had a kidney transplant.
